To to whom it may concern.-

Be it known that 1, Manatee HnLtwio. a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Inserting Bristles'into Brush-Backs, of which the following is a full, clear, and exact description.

machines for inserting the bristles into brushbaeks to form the brush; and the mechanism here shown is specially adapted for the 1nannfacture of brushes ot' the kind described in two separate applications for Letters Patent filed by me on even date herewith, and designated as Cases A and G, having Serial X0. 107,096 and No. 107,098, respectively.

The invention consists in the details here inat'ter described, and particularly pointed out in the claims.

In the accompanying drawings, in the several figures of which like parts are designated by similar letters oi reference, Figure l is a perspective view of a press having my improvements attached thereto. Fig. 2 is a longitudinal section through the plungers, receptacle i'or bristles, brush-back, and gage or form. Fig. 3 is a longitudinal section through the receptacle for bristles. Fig. :1.- is a detail view of the plungers, and Fig. 5 is aplan vicw of the plungers.

A designates a i'ootpress of the usual construction, having a slide-bar, B, driven by means of a lever, O, to which motion is communicated from the foottreadlc D by a pit.-

tcniovably attached to the slidebar i3 is a plate, F, which can be connected to the slidebar by any suitable die-clamp, such as are G- designates a number of plunger-s fixed to the under side oi the plate F. These plungers, as here shown, consist of a series of cylindrical rods of a diameter sufficient to enter the holes side of the brush-back.

; desired shape and size, having a cover a. designates a recep taele for the bristles, consisting of a box of any adapted to be opened and closed. The top of this box is provided with a series of holes, Z), and the bottom with a series of holes, I), the holes I) 6 being in line with each other, and of the same number, size, and shape as the plungers G. This invention relates to improvements in Into one end of the box a is arranged a close-fitting partition, 0, which is held upright by means of a tongue fitting into a groove, (Z,

in one or both sides of the box. one end against the end of the box, and at the other against this partition 0, are powerful springs (2, whereby the partition 0 is auto matie ally moved up, to keep the bristles f in 7, corresponding to the packed with a I clamps L, or in other commonly employed for this purpose in stamp- 'ing-presses.

7 all in direct line.

a solid mass as fast as a ii uantity is forced out 1 by the plungers.

1/ designates that part of the brush-back to which the bristles arc to be attached, and h the gage or form. The brush-back has a series of holes, 1?, extending through it, corresponding in number with those in the receptacle a, and the gage or form 71 has a central cavity to receive the brush-back, and a series of holes,

holes *6 in the brushback.

The operation is as follows, viz: The plate F, carrying the plungers G, is fixed to the slidebar B of the press A. The receptacle a is solid mass of bristles or hair arranged edgewise, the partition cbeing moved back as far as the tongue and groove will per- .nn't it to go. The brush-back g is placed on the gage or form, fitting into the central cavity, so that its holes t are brought in line with the holes j. The brush-back and gage or form are then secured to the receptacle c by suitable manner, so that the holes i in the bruslrback are brought in line with the holes I) inthe bottom of the receptacle a, thus bringing the holes b, Z), r, and

The receptacle a, brushbacl; 1 and gage or form 7 are placed on the bed-plate of the press and secured in place, so that the plungers G are in direct line with the holes I) in the top of the receptacle a. By pressing the trcadle D down, motion is communicated to the pitinan E, and thence to the lever O, and the slide-bar B is operated to force the plungcrs down through the holes I) b. As the plungers pass through the receptac1e a,

Bearing at operation of the plungers.

they force the desired quantity of bristles or hair out through each hole I), through the holes 2' in the brush-back, into the holes j in the gage or form. When the pressure is released on the treadle D, the slide-bar 13 moves up, carrying the plungers up and out of contact with the receptacle, and the springs c then operate to move the partition forward, to keep the bristles in a solid mass for the next The holes in the gage or form are of a depth sufficient to give the bristles forming the brush-back the requisite length to form a brush, while the tubular portions H of the plungers leave a small portion projecting through each hole in the brush-back, and above the same, so that the bristles can be attached to the brush-back.

' After the operation of the plungers, the gage or form and the brush-back are removed from under the receptacle a, and the bristles are at taehed to the brush-back before the same is taken off the gage or form.

It will be seen that the bristles to form the brush are inserted into the holes formed to receive them in the brush-back at one operation of the press, thus saving much time and labor.

When a series of slots are employed in the brush-back for the bristles or hair, instead of circular holes, the plungers will be made of the desired shape and size, and the receptacle and the gage or form will be slotted to correspond therewith.

I am aware of a machine for the manufacprovided with plungers adapted to force bristles or hair into the brush-back through a tubed holder for such bristles or hair, the said holder being constructed of two plates provided with grooves which match when the plates are clamped together to form the tubes.

I am also aware that a bristle-holder has.

been made with fixed partitions, to keep the bristles upright while said holder was being used to fill a brush-back.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a machine for the manufacture of brushes, the combination of a receptacle for bristles or hair, having a series of holes in its top and bottom in line with each other, with a close-fitting partition, andmeans to automatically move it forward against the bristles in the receptacle,whereby said partition serves to keep the bristles or hair in an upright solid mass, substantially as herein shown and described.

2. In a machine for the manufacture of brushes, the combination of a number of plungers, a receptacle for bristles or hair, having a series of holes in its top and bottom made in line with each other, a partition in said receptacle adapted to move automatically against the bristles, to keep the same upright and in a soldid mass, and a brush-back gage or 'form having holes corresponding to the holes of the bristle-receptacle, all substantially as shown and described.

In testimony whereof I have hereunto set my hand this 18th day of September, A. D. 1883.
